The next step in the Corn rocket family is the CornRoc a 18mm rocket



Leaving the Foam Corm out the componets are sinular to the A-corm with the same quality conrtol




The slots for the fins like the A-Corn are cut with a 1/8 Dreamel tool and angle iron.



The fins are cut out from two sheets of balsa.
the Template was traced onto Heavy cardstock to save from cutting instructions.




fitting the nose block in place before glueing into the nose cone.

CornRoc on the pad




Chute tangled slightly but no damage to the rocket



Close up of the tangled shrouds caused by a delay that took longer then stated

I think I'll go on record here and re-specify motors.

B4-2, B6-4, C6-3 only. Well, you could use a RMS 18mm D if you get it to balance. The shortest delays you can get in BP and I suggest Rocksim for the RMS delays. The foam corn is heavier than it looks and most must be heavier than my prototypes, so my bad on that.

I intend to do more testing on these designs and release them again this Fall under my new company.

Stay tuned.
